3.2 FDMQ, FFQ Series
Outline
Make sure to install the decoration panel before carrying out trial operation if the wireless
remote controller is used (FFQ series only).
Trial operation should be carried out in either cooling or heating operation.
1. Measure the supply voltage and make sure that it is within the specified range.
2. In cooling operation, select the lowest programmable temperature;
in heating operation, select the highest programmable temperature.
3. Carry out the trial operation following the instructions in the operation manual to ensure that all
functions and parts, such as the movement of the flaps, are working properly.
To protect the air conditioner, restart operation is disabled for 3 minutes after the system has
been turned off.
4. After trial operation is complete, set the temperature to a normal level (26°C to 28°C (78°F to
82°F) in cooling operation, 20°C to 24°C (68°F to 75°F) in heating operation).
When performing field settings or trial operation without attaching the decoration panel, do not
touch the drain pump. This may cause electric shock.
After finishing the construction of refrigerant piping, drain piping, and electric wiring, conduct trial
operation accordingly to protect the unit (FFQ series only).
Procedure
When operating the air conditioner in cooling operation in winter, or heating operation in summer,
set it to the trial operation mode using the following method.
